Question 1002656
(A)
Only the right hand member will be different; the line is to be parallel.
{{{3x-7y=3*(-6)-7*10}}}
{{{3x-7y=-18-70}}}
{{{highlight_green(3x-7y=-88)}}}
-
If you want in point-slope form, the slope is  {{{3/7}}}.
Equation:  {{{highlight(y-10=(3/7)(x+6))}}}, directly plugging the values into the equation form.



(B)
You could convert if you want, starting from the found point-slope form of the equation, but the use of standard form was done first, using some knowledge of how standard form works.
